This invention relates to a device for compacting a plurality of wound bodies or masses of threads, and more particularly to a device for compacting bodies of artificial silk threads in a condition to permit the forming of a unit cornposed of a plurality of wound of the thread.

In the past difficulty has been encountered in the transportation of uncompacted bodies or masses'of artificial silk and the like due to the fact that such bodies or masses are of circular formation and packages thereof were for this reason extremely bulky. Furthermore, packages of such bodies which permit freedom of movement of the threads allow the threads to become somewhat entangled or otherwise damaged.

To overcome the difiiculties heretofore encountered it is now quite customary to prepare the artificial silk for shipment by rewinding the bodies or masses threads from the bobbins or cakes into the form of tightly wound cones. However, this practice is objectionable because of the circular formation of the cones and the resultant bulkiness of the packages and for'the reason that the additional rewinding step involves the increased handling of the thread and consumes considerable time and labor.

It is an object of the present invention to overcome the difiiculties heretofore encountered in the conditioning of wound bodies and masses of artificial silk thread for treatmentor shipment.

This invention also contemplates the'production ofa compact package of artificial silk bodies or masses wherein the threads in the various masses are maintained in a protected condition and do not become entangled.

It is a further object of this invention to provide a device by which a plurality of wound bodies or masses of artificial silk may be compacted.

Other objects and advantages will be apparent from the following detailed description when considered in connection with .the accompanying drawing wherein Fig. 1 is a perspective view of a device constructed in accordance with this invention for compacting and securing a plurality of wound the device as illustrated in Fig. 1, in which the compacting portion is duplicated and the power is applied thereto intermediate of these portions.

Now in referring to the drawing in detail, the numeral l0 designates a trough shaped receptacle having an end ll partially closed by abutments 12 extending from the respective side I At the end opposite to the abutments l2, the

trough I0 is open. and a pressure plunger I! is .shaped to fit into the trough for movement toward and away from the abutments l2. Pressure plunger I1 is provided with a connecting rod l8 which is adapted to connect the plunger with a source of power (not shown) by means of which the plungen is caused to be moved in the manner set forth.

The pressure plunger H has a forward face l9 divided so as to form separated contact sur-- faces with a slot therebetweencorresponding in size and position so as to form a continuity of slot l6 in bottom l5 when the plunger is in position over the slotted portion of the bottom of the trough lil. Behind the face l9 plunger ll is hollowed out as at-20 for the reason to-be hereinafter referred to.

In the construction illustrated in Fig. 4, two 3 troughs I0 are shown provided with pressure plungers l1, and these plungers are joined by common means I8 for connecting them with the source of power. It will be seen that in the operation of the structure illustrated in Fig. 4, one of the plungers will be moved toward the abutments I2 of the trough in which it operates while the plunger in the other trough is moved to a position for loading its respective trough.

In practicing the invention according to either device, the pressure plunger in the trough being utilized is retracted and a plurality of circular bodies 2| of artificial silk or the likeare placed in the trough in front of the plunger.

Power is then applied to cause the plunger to be moved forward and to thereby collapse and compress the bodies 2|. When the bodies 2| are compressed, as indicated in Fig.3, a tie 22, preferably formed from a broad flat piece of binding material, is passed around the bodies and in contact therewith due to the space provided by the respective slots l4 and I6 and the slot in the plunger, whereupon the tie is knotted and the bodies 2| are adapted to be removed from the trough as a unit.

It will be seen that the hollowed portion of the plunger permits of ease in passing the tie therethrough so that the tying may be practiced quickly and efilciently. As a further convenience, the tie 22 may be drawn from a roll of the binding material arranged above the trough and a cutting device may be provided adjacent thereto, the roll and cutting device being illustrated diagrammatically in Fig. 1 without being otherwise illustrated. v

The practicing of the invention as described is similarly carried out in connection with the structure illustrated in Fig. 4 except that one trough is loaded with bodies 2| during the tying of com pacted bodies in the other trough, and this operation is repeated by compacting and tying bodies in first one trough and then in the other as they are compacted during the reciprocation of the respective plungers. I

The units of tied compacted bodies are preferably prepared for shipment by placing a plurality of the units in a packing case which is linedwith paper, sheets of paper also being placed between every two layers of packages within the packing case.

What I claim is:

An apparatus for flattening collapsible masses of artificial silk and the like to permit the tying thereof into a unit comprising a body portion having a substantially horizontal bottom and side walls extending thereabove acting as a receiver and guide for a plurality of collapsible masses of artificial silk, an abutment at the end of the body against which an end mass is adapted to bear, said abutment being integral with the receiver and entirely divided to provide a freely accessible slot and the body portion being provided with a longitudinal slot adjacent the abutment corresponding to and in alignment and forming a continuation of the slot in the abutment, a hollow pressure plunger also having a slot therein in alignment with the two aforementioned slots and arranged for movement within the body portion and being adapted to be moved to a. positionwherein the plunger slot
